Dermatophyte Test Medium (DTM)

Dermatophyte Test Medium (DTM) is a specialized laboratory growth medium used to identify fungal infections caused by dermatophytes—fungi that infect skin, hair, and nails. When a sample is placed on DTM and incubated, it provides nutrients that support fungal growth. If dermatophytes are present, they typically cause the medium to change color (often to red), indicating a positive result. This helps healthcare providers diagnose fungal infections precisely and quickly. DTM is a valuable, efficient tool in diagnosing dermatophyte infections, aiding in appropriate treatment decisions.
